while they are broader and thinner with a small number of palisade cell layers in dry environments.Based on these, we argue that broader and thinner leaves of C.procera dissipate incident energy at the expense of a higher rate of transpiration to survive in environments in which water is the...
Subnival glasshouse plants provide a text-book example of high-altitude adaptation with reproductive organs enclosed in specialized semi-translucent bracts, monocarpic reproduction and continuous survival under stress. Here, we present genomic, transcrip
Counts were made on both surfaces of the leaves for a total of 40 counts per experimental group. Twenty histological median cross-sections randomly collected from 10 leaves per plant accession were used for the determination of total leaf thickness (TLT), palisade parenchyma thickness (PPT), ...
aA mature noble rhubarb plant in the Hengduan Mountains (N28.53°, E99.95°; Elev. 4500 m) with insert showing a morphological comparison between a photosynthetic basal leaf and a translucent leaf.bSpectral characteristics of bracts and leaves in light transmittance, showing the different patterns...
Besides spongy tissue,there was another kind of special mesophyll tissue “semi palisade tissue” in asssimilating tissue constituted with layers of elongate cells,whose macro axis was paralle with the leaf epidermis,and it means a significantly enlarged photosynthetic tissue area,suggesting an ...
Basic types of changes in mesophyll structure, associated with plant adaptation to mountain conditions, were characterized. These changes manifested themselves in different numbers of cell layers and cell sizes in the palisade tissue and, as a consequence, in changed leaf thickness and cell number ...
